Darkness is hitting me particularly hard this fall. It doesn't help that we've reduced the lighting in the office to save money. The low-wattage CFL bulbs at home leave everything slightly dim as well. It wasn't as bad when I spent a lot of time outside in Summer, but it's fast approaching the days when I both arrive at and leave work in darkness. You southern climate folks have no idea what it does to your brain and body to only experience a few weak hours of sun each day (if any), with nothing but dim fluorescent bulbs in between.
So I decided to compromise my frugality and environmentalism for the sake of having enough energy to function. I can't afford a $300 SAD lightbox, but I can (luckily) afford $30 in high-wattage daylight spectrum bulbs. JD helped me rig up a couple of freecycle table lamps on a timer with 300 watt incandescent daylight bulbs so that at 6:30 in the morning it looks like the sun has risen in the bedroom. The bulbs go off on the timer at 7:30 when I leave for work. I put 100 Watt incandescent daylights in the bathroom as well, and will head to the Habitat Re-Store today in search of floor lamps to brighten the living room.
I'm probably still not getting the full 10,000 lux of full daylight, even if I'm managing 10,000 lumen with the bedroom lights. I'm also, before someone brings it up, starting a vitamin D regimen and trying to be outdoors on my lunch hour.
I still feel guilty over giving up the energy savings of CFL's, but I can always swap them out during the summer when I can open windows for more ambient light. Until then, I think I just have to compromise ideals for functionality.
